Doc #54088 [Opn]: Some unicode chars not being displayed in IE.

Edit report at http://bugs.php.net/bug.php?id=54088&edit=1 ID: 54088 Updated by: rquadling@php.net Reported by: rquadling@php.net Summary: Some unicode chars not being displayed in IE. Status: Open Type: Documentation Problem Package: Documentation problem Operating System: N/A PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Using Windows XP SP3 (my local machine) and a Windows Server 2003 R2 Standard Edition (One of my VM-d dev servers - used for php-src) using IE8.0.6001.18702 also. On Windows Server 2008 Enterprise (another VM-d dev server used IIS7 Development) using IE8.0.6001.19019, the ℤ is shown. Cutting and pasting from a working IE into MS Word reveals that the font is Cambria Math. If I do the same exercise with Chrome and Firefox, the same font. Doing this from my local IE8 (where the incorrect glyph is displayed), the copied data is pasted correctly and shows as Cambria Math. So it seems to only be IE8.0.6001.18702. I've no idea about older versions.

On Win7 I can see the "ℤ" in Internet Explorer 8.0.7600.16385. Of course it looks better with "Arial Unicode MS". I don't know which replacement font IE is using (looks the same like this character in the bug tracker with Firefox. Regards, Carsten ------------------------------------------------------------------------ [2011-02-24 12:50:50] rquadling@php.net Description: ------------ On http://docs.php.net/manual/en/language.types.integer.php, the first line reads ... "An integer is a number of the set ℤ = {..., -2, -1, 0, 1, 2, ...}." In Google Chrome V11.0.672.2 dev and in Firefox V3.6.13, the ℤ (a Double-Struck Capital Z :: ࡌ) is displayed correctly. In IE8.0.6001.18702, the character displayed is the usual box character for an unknown glyph. This is also true in the downloaded CHM files (as they use IE to render the page) as well as all the compatibility and quirks mode (tested within IE8). It seems that the font being used is Arial. In the Arial font on my machine (V3.00 and digitally signed to be an authentic font), this glyph is not present. Adding "Arial Unicode MS" to the font-family, then this character is displayed correctly. The issue is not an encoding issue. The character is correctly encoded. It is just the font being used by IE doesn't have the glyph. But replacing the entire site's font isn't something I'd like to do just to fix what so far is 1 character. One way would be to change the ℤ to a Z. http://en.wikipedia.org/wiki/Integer says this is one way this symbol is shown. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54088&edit=1
